I just picked this amp up and loving it so far. I am working to port some of my metal patches over from previous setups and admittedly have struggled a little bit to dial things in. This being said here is V1 of my Metallica MOP patch. Feel free to adjust to your liking and feedback is welcome.

Hi! I just got the Katana 100. For sure it’s a great amp, bur i’m Noticing that it make a lot of background noise as soon as I go to crunch, lead or brown (brown really makes a lot of noise). And I don’t think it’s for ground loop, it’s the typical “sssccchhh” of gain amps. Did you also experienced that, dealing with high distortion? What do you suggest to limit it? Thank you and congratulations!
